"We see more and more interest in these wines from wine enthusiasts who believe NSA wines provide the most pure expression of the grape and from those who have sulfite sensitivities and allergies," said Geof Ryan, national wine buyer for Whole Foods, in a statement.

Approximately 10 to 20 wines per Whole Foods location are organic NSA wines. The retailer sources domestic varieties from Roule Rouge in Northern California, and Frey Vineyards in Mendocino County, Calif., which produces such wines as an organic red, white and rose as well as true varietals like organic chardonnay and petite syrah.
